Characterization of anisotropic behaviour of ZK60 extrusion under stress-control condition and notes on fatigue modeling
Pahlevanpour, A.H.; Behravesh, S.B.; Adibnazari, S.; Jahed, H. (Elsevier, 2019-10)The anisotropic fatigue behavior of ZK60 is investigated through stress-control tests along two different material directions: extrusion (ED) and radial (RD) directions. The in-plane random texture along RD promotes ... -
Characterization of magnesium spot welds under tensile and cyclic loadings
Behravesh, Seyed Behzad; Jahed, Hamid; Lambert, Steve (Elsevier, 2011-12-01)Resistance spot welds of a magnesium alloy were characterized in terms of microstructure, hardness and monotonic and cyclic properties. Microstructural features in base metal and different zones in the weld region were ... -
Effect of forging on the low cycle fatigue behavior of cast AZ31B Alloy
Toscano, Dwayne; Shaha, Sugrib K.; Behravesh, Seyed Behzad; Jahed, Hamid; Williams, Bruce W. (Elsevier, 2017-08-26)The effect of forging on the low cycle fatigue (LCF) behavior of cast AZ31B was investigated. The forging process was conducted at a temperature of 450°C and speed of 390mm/min. Fully reversed (Rε=-1) strain controlled ... -
Fatigue characteristics and modeling of cast and cast-forged ZK60 magnesium alloy
Karparvarfard, S. M. H.; Shaha, Sugrib K.; Behravesh, Seyed Behzad; Jahed, Hamid; Williams, Bruce W. (Elsevier, 2019-01-01)The fatigue behavior of as-cast and cast-forged ZK60 magnesium alloy was investigated via fully-reversed strain controlled fatigue tests at different strain amplitudes. Microstructure analysis, texture measurement, and SEM ... -
Fatigue Characterization and Cyclic Plasticity Modeling of Magnesium Spot-Welds
Behravesh, Seyed Behzad (University of Waterloo, 2013-07-18)The automotive industry is adopting lightweight materials to improve emissions and fuel economy. Magnesium (Mg) alloys are the lightest of engineering metals, but work is required to assess their structural strength, ... -
Fatigue characterization and modeling of AZ31B magnesium alloy spot-welds
Behravesh, Seyed Behzad; Jahed, Hamid; Lambert, Steve (Elsevier, 2014-07-01)Cyclic behavior of AZ31B spot-welds was studied using different specimen configurations, and compared with steel and aluminum spot-welds. Fatigue strength of magnesium spot-welds was similar to aluminum and less than steel. ... -
Low-cycle fatigue characterization and texture induced ratcheting behaviour of forged AZ80 Mg alloys
Gryguc, Andrew; Behravesh, Seyed Behzad; Shaha, Sugrib K.; Jahed, Hamid; Wells, Mary; Williams, Bruce W.; Su, Xuming (Elsevier, 2018-11-01)Stress-controlled uniaxial “push-pull” fatigue testing was conducted on as-received (cast and extruded) and closed-die cast-forged and extruded-forged AZ80 Mg alloy. The as-cast material possessed random texture and somewhat ... -
Microstructure, texture and mechanical behavior characterization of hot forged cast ZK60 magnesium alloy
Karparvarfard, S.M.H.; Shaha, Sugrib K.; Behravesh, Seyed Behzad; Jahed, Hamid; Williams, Bruce W. (Elsevier, 2017-04-14)Uniaxial tension and compression tests were conducted to investigate the quasi-static performance of ZK60 Mg alloy in cast, followed by forging at optimum temperature of 450°C and a ram speed of 39mmmin-1. Microstructure ... -
Monotonic and cyclic behaviour of cast and cast-forged AZ80 Mg
Gryguc, Andrew; Shaha, Sugrib K.; Behravesh, Seyed Behzad; Jahed, Hamid; Wells, Mary; Williams, Bruce W.; Su, X. (Elsevier, 2017-11)Tensile and strain-controlled fatigue tests were performed to investigate the influence of forging on the performance of cast AZ80 magnesium alloy. The obtained microstructural analysis showed that the as-cast AZ80 magnesium ...
